SRM upgrade from ECC to S4 HANA - master data replication issue

Dear Team,

We have recently upgraded SRM to 7 and interfacing with S4 HANA 1709.

We have done all the connections, but the master date replication is not happening.

COM_CATEGORY_TRANSPORT gives the below error:

R3MATGRP Business partner with GUID XXX does not exist

Table COMC_LOGSYS_MAP is maintained with Source -> SRM ; Target -> S4 HANA

Thanks in advance.
